1. Field of the Invention
The present invention is directed to an apparatus and method for programming and controlling the operation of a washing machine. The washing machine is provided with a set of pre-programmed slates, each including a number of different cycles. Each slate is specifically designed for use in a particular environment, for optimal cleaning of a specific type of fabric used in that environment. Although the system is installed with a specific slate, the system is designed to allow for the use of additional slates. Additionally, the individual cycles present in a slate may be selected from among all of the cycles present in all of the slates. Furthermore, the specific parameters and functions of each cycle may be re-programmed on site.
2. Discussion of the Prior Art
Automatic commercial washing machines have traditionally been operated from stored programs selected through manually actuated buttons or knobs. There is known in the art of washing machines a large number of electronic control systems which arrive from the factory with a variety of settings. These settings often include wash temperatures and time settings for various operations performed by the washing machine. Commonly present in modern washing machines are settings which optimally clean different fabrics. Depending upon the type of fabric chosen, the settings direct the various operations of the washing machine. It is also known in the art to provide on-premise laundry systems with pre-programmed operational cycles. Frequently, these pre-programmed operational cycles are organized into a series of slates which gives a user a number of different cycles from which to choose.
Because the cycles are pre-programmed at the factory, each machine is specifically designed for a particular environment. Typically, a machine will be pre-programmed with cycles relating to the types of fabric usually found in that environment. For example, a machine may be programmed with a slate directed to the fabrics found in a hotel, hospital, restaurant, or health club. Because the types of soiled fabrics differ in each environment, each slate will be specifically tailored to the types of fabric used and typical stains found on the fabrics in that environment.
The machines come pre-installed with a specific slate of cycles. For example, if a machine is to be used in a hospital, the cycles from which the user may choose are pre-programmed to optimally clean the fabrics typically used in a hospital setting. If the machine were to be used in a health club, the cycles may differ because the typical fabrics and stains encountered in a health club differ from that of a typical hospital. Therefore, the various cycles available are preset at the factory or by the installer depending upon the expected location and use environment of the machine.
U.S. Pat. No. 5,585,704, to Elzind teaches incorporating a microprocessor based control system into a washing machine in order to allow the changing of cycles after installation. The system replaces the pre-existing manual operation push buttons with a module connected to an automatic controller. The controller includes a circuit which incorporates a series of manual push buttons. Through the manual push buttons, the user is able to select between various wash programs. The controller also includes a removable and replaceable solid-state memory card which stores multiple wash programs. These memory cards, once inserted into a memory card drive present on the machine, provide multiple wash programs to the machine, allowing the archiving and up loading of various wash programs. Although the system allows the change of the various programmed wash cycles, the selection of wash cycles is limited to those present on the memory cards. Additionally, such as system requires external peripherals to add additional settings.
In any event, users are limited to the current slate programmed into the machine. Although it may be possible to load other cycles into the machine, it is difficult to change each of the cycles for optimal use in another environment. Additionally, a new slate of cycles cannot be easily loaded into the machine. Furthermore, with conventional washing machines, changing the individual parameters, other than a single wash cycle, is difficult at best.
The present invention is particularly directed to an apparatus and method for programming various slates and cycles of a washing machine. Generally, the present invention allows the editing of programs present in memory of the washing machine. The machine comes pre-programmed from the factory with different slates, each designed for use in a particular environment, with varying cycles programmed therein. The combination of cycles chosen for each slate relates to the expected requirements of use in each of the environments.
The washing machine of the invention is provided with a display and a series of buttons, forming a keypad, for selecting a desired cycle. Simply pressing one of the buttons starts the cycle selected. Because the washing machine comes pre-programmed with numerous slates and a selected slate for the expected environment, the washing machine therefore comes installed ready for use. If, however the user wishes to choose a different slate, this can be accomplished through the display and keypad. This allows the complete replacement of each of the cycles available.
In other situations, the user may wish to keep a majority of cycles present in the current slate, but replace others. It is possible in accordance with the invention to select cycles present in other slates, and place them in the current slate. By doing so, the user is granted a much larger degree of variability of the cycles available for use. Additionally, the user is given the ability to pick and choose cycles from the different slates pre-programmed into the washing machine to build a new slate. This allows a complete reprogramming of the current selected slate. Although the text associated with each of the buttons does not change, the assigned function does.
Each cycle comes pre-programmed from the factory with set parameters and operations. The parameters include, but are not limited to, cycle duration and temperatures, while the operations include, for example, dispensing and spinning modes. However, the user is not restricted to the pre-programmed parameters and operations. Through the buttons and display, it is possible to edit the pre-programmed parameters and operations of each cycle. Thus, each cycle may be completely rewritten with new commands.
Based on the above, it is possible to edit the currently available slate of cycles of a washing machine in accordance with the invention by (1) selecting an entirely different slate from among other available slates that have been pre-programmed into the machine; (2) editing the current slate by replacing one or more of the pre-programmed cycles in the current slate with cycles in other pre-programmed slates; or (3) editing the individual parameters and operations of one or more cycles of a slate to create cycles not present in any of the pre-programmed slates, thereby creating an original cycle to be used in the current slate.
In general, the invention represents an extremely versatile programming arrangement which allows system customization on a variety of levels. Additional objects, features and advantages of the invention will become more readily apparent from the following detailed description of a preferred embodiment thereof, when taken in conjunction with the drawings.

As shown in
The description of the invention to this point has been essentially provided for the sake of completeness. In general, the invention is particularly directed to enabling a laundry machine to be programmed on various different levels as will be detailed hereinafter. When washing machine 1 is installed, the programmer either accepts a default slate or chooses a new slate, depending upon the expected use of washing machine 1. For example, a food service establishment generally requires a different slate of cycles from those required by a health club. Preferably, washing machine 1 is pre-programmed with a variety of industry slates, each designed for a specific industry: general use, hotels and motels with food service, hotels and motels without food service, health care with food service, health care without food service, general food service, fast food service, athletic club or beauty salon, and shirt laundry. The cycles of the pre-programmed slates have been chosen at the factory based on the expected needs at each of the above laundry facilities. Through buttons 12–17, one of the pre-programmed cycles of the selected slate is activated. The following tables illustrate a preferred combination of pre-programmed slates, along with their cycles, which may be chosen by the programmer upon installation of washing machine 1:

Although the above cycles are each shown as having not more than ten steps each, it is possible, via CPU 20 to have extra steps added. Additionally, a drain and spin step preferably occurs between steps except prior to a Carryover step. As can be seen from the above tables, the individual steps used in each of the cycles can be chosen from a short list of procedures, including:

From the above, it should be readily apparent that washing machine 1 is initially provided with various stored slates which enables any given machine 1 to be adapted for use in a wide range of environments. That is, a desired slate can be selected from a plurality of slates which enhances the versatility and functionality of the machine 1. In addition, each slate can be modified on various levels. Particularly, the pre-programmed cycles in one slate can be substituted for another. In addition, the operational parameters associated with any given cycle can be altered. In this way, a new slate can be established on multiple levels. In any event, although described with reference to a preferred embodiment, it should be readily understood that various changes and/or modifications could be made to the invention without departing from the spirit thereof. For instance, although
